The Precious, Wonderful, Adorable, Loveable Duckling - Season 1,Episode 10

Courage finds a duck egg, brings it inside, and gives it to Eustace. Eustace thinks he is going to eat it for breakfast, but finds out its still alive. It hatches and thinks Eustace is his mom. The duck becomes "Eustace's slave" and it's jealous of Muriel and Courage, which makes it do nasty tricks on both. Courage eventually puts a stop to this, in which the duck straps Muriel on a rocket headed for the moon. Muriel gets off it by the help of Courage, but the duck can't get off because his arm is trapped under the hood of the rocket. Eustace goes upstairs to help the duck, grabbing onto the rocket. Then, all of a sudden, the rocket takes off, heading towards the moon with Eustace and the duck on it.
